e.g. The Grand Canal. Canal-transport continued to play an important economic role in the link between north and south China, and the upkeep and expansion undertaken during the Ming dynasty was continued under the Qing in varying degrees.
[1]
At the end of the Grand Canal was Hangzhou, connected with Ningbo port through the Eastern Zhejiang Canal, which served as the economic lifeline of the development of Hangzhou. The key to this development was the connection between the water system in the city and the outside through canals and irrigation networks.

Overall, the canal systems declined drastically near the end of the Qing with increased silting in the Yellow River. The Board of Works was responsible for maintaining all official buildings, granaries, official communication routes, dykes, dams, and irrigation systems.

’Archaeological research at Oc Eco in Vietnam and Angkor Borei in Cambodia, two walled and moated urban centres linked by a canal system, have revealed the adoption of Sanskrit names for kings, use of the Bhrahmi script, worship of Hindu gods, and adherence to the teachings of the Buddha, wooden statues of whom have been uncovered, containing pits for cremated human remains. Grave offerings found in these pits include gold plaques embellished with sacred Buddhist inscriptions and images of Hindu deities.’

’In the 1920s Pierre Paris overflew this area [the flat plains surrounding the Mekong and its Bassac arm below Phnom Penh] and took a series of photographs. These revealed a network of canals crossing the landscape, and various nodal points where they met. One such junction revealed a huge enceinte demarcated by five moats and ramparts encoding 1,112 acres (450 ha). It was here that Louis Malleret excavated in 1944. The site was known as Oc Eco [...].’

’The Funanese had already built a canal network near their port, and a canal 90 km long linking their port to an inland city, Angkor Borei, in which channels and bray were constructed for flood control and dry-season water supply, but the canal is considered to have been for transportation, and within a trading polite, not for irrigation.’
[3]
’Clearly Funan’s rise had two sources: the productivity of its agrarian system and the area’s strategic location opposite the Isthmus of Kra. A network of canals connect the coast to Funan’s agricultural upstream, centered on its urban ‘‘capital’’ at the archeological site of Angkor Borei in modern southern Cambodia. It is unclear whether this canal network required a new level of techno- logical competence or a central leadership for its construction (Malleret:1959-1963; Liere: 1980; Stark: 1998, 2003, 2006a, 2006b; Stark and Sovath: 2001).’

’The FUNAN maritime state (150-550 C.E.) was responsible for the con- struction of an extensive canal network, and at its main center of ANGKOR BOREI the EASTERN BARAY covers an area of about 200 by 100 meters (660 by 330 ft.).’

Suez Canal which linked the west and east of the empire by sea was already planned by the Egyptians and was finished by Darius I.

Darius ordered a canal dug between Red Sea and the Nile; the commemorative stela suggests his primary transit interest was ’from Egypt through this canal to Persia’.

Construction of large irrigation canals (e.g. Dargom, Bulungur, Narpai and Shahrud) on the Zaravshan (the Salar canal in the Tashkent oasis) have been dated to the Kushana empire.

Were these canals used for transport? "The surviving portions of a canal of the K’ang-chu period (fourth century b.c. to first century a.d.) measure as much as 20 m from bank to bank; those dating from the Kushan period (second and third centuries a.d.) measure only 10-11 m, but have steep sides and are much deeper."

"During and after the conquest of the Song, Bayan Chingsang (Grand Councillor Bayan) achieved legendary status. Chinese songs and folklore spoke of him as “Hun- dred Eyes” (bai yan in Chinese), and his red banner could incite panic in Song troops by its sudden appearance. Even so, Qubilai’s chief mandate to Bayan was to kill no more than necessary, and Changzhou was the only city where he ordered wholesale massacre. In 1311 a temple was dedicated to him in Lin’an by imperial decree. During his stay in the south, the development of water transport, both inland and overseas, had impressed him, and in 1282 he advocated both the construction of canals in the north and the overseas transportation of southern grain to the capital. These proposals bore fruit, however, only after he had been dispatched to the Mongolian frontier."

The following quotes suggest that there is not much evidence for the use and construction of canals in this polity at this time, with the partial exception of Charlemagne’s failed Fossa Carolina project. However, the fact that Charlemagne could conceive of such a project and attempt suggests that perhaps smaller canals existed.
“Even more grandiose—if failed—the Fossa Carolina project, a canal connecting the Danube and Rhine rivers, underscores Charles’ vision of the eastwar extension of his empire (Figures 13.1 and 13.2). […] With or without canals and major bridges, the rivers of northern Europe offered comfortable travel for people and cheaper transport for bulk goods. Charlemagne and his family sailed down the Rhine, Frisian merchants were towed up it, and countless lesser streams bore boats. Such traffic stmulated the growth of small riverbank settlements, the portus.” [1] “During the Early to High Medieval period (cf. Table S1) the entire region between Denmark and Italy was controlled by powerful elites which were extraordinarily mobile, building up itinerant kingships and huge economic networks controlled by religious institutions [5]–[8]. Freund [9] highlights the important role of Central European river valleys for the communication networks of these groups. The basic work of Eckholdt [10] features methodological problems. Here, the role of the small rivers seems to be underrepresented [11]. until now there is poor knowledge about the location of inland ports, the explicit medieval navigability of the rivers and the bridging of watersheds between these rivers and their catchment areas [12]. So far there is mainly evidence for small and simple constructed medieval inland ports and hythes [13], [14].” [2] “At the time when the Grand Canal of China was completed, water-transport in Europe was still in a primitive state. Few canals had been constructed, and rivers were chiefly used as a source of power for water-mills. On many rivers each mill had its weir, to provide an adequate head of water for the mill-wheel, and these weirs were a serious obstacle to navigation. In the later Middle Ages, however, important developments took place in the Netherlands, as we shall see, while throughout the more commercially active countries of Europe improvements were made in the rivers by building stanches in the weirs and also at intervals along the river, between the mills, to reduce the gradient and increase the depth of water in the shallow places [3]. […] The early history of stanches is obscure, but it is practically certain that they were in existence on a number of rivers in Flanders,1 Germany, England, France, and Italy before the end of the thirteenth century.

The Hmong relied on natural waterways: ’Roads. - The communication system in the Miao area consists of land routes and waterways. The most important waterway is the T’ung Ho, because it is navigable for a comparatively long distance, and it goes deep into Miao country. This river starts at Lu Ch’i and goes toward the mouth, extending 17 li to Su-mu Ch’i, ten more li to Hsien-ch’i-t’ang, another 21 li to Nung-t’an, 15 more li to T’an Ch’i, ten more li to Ta-pi-liu, another ten li to Ch’e-ch’i, and 30 more li to Ho Ch’i. From the mouth of the river to Ho Ch’i, some 130 li, the waterway is known as the Wu Ch’i River. Above Ho Ch’i it divides into two branches, south and north: the northern branch, known as the Wan-yung Chiang, runs ten li to Chang-p’ai-chai, where it again divides into two more branches, one flowing westward as the Wan-yung Chiang proper, passing through Ta-chuang and Hsiao-chuang for 50 li to Kan-ch’eng. The other branch, which flows northwestward, is known as Kao-yen Ho, and goes 15 li to Chen-ch’i-so, 15 li to Hsienchen-ying, ten li to Chen-ning-ying, 20 li to P’ing-lang, five li to Wei-che, eight li to Hsün-chien-p’ing, 20 li to Kao-yen-hsin. The branch flowing south of Ho Ch’i, known as the T’o Chiang, flows through Ch’i-k’ou, Chiang-chün-yen, and Mao Chou to Lao-hu-k’ou for about 60 li, and then passing Lao-hu-k’ou it flows from Mu-lung-ti Chiang to Feng-huang for another 70 li.’
[1]
’The parts of the T’ung Ho navigable by small craft are: the Wu Ch’i, 113 li; the Wan-yung Chiang, 60 li; /Illus. 16, 17 on pp. 42, 43/ the Kao-yen Ho, 93 li; and the T’o Chiang, 130 li; totaling 296 li in all. These river courses are difficult to navigate and are not passable all year round. Miao Fang-pei Lan in the section on roads and waterways says: “This river (the T’ung Ho) has precipitous cliffs standing up like daggers, strange rocks clustering like a forest of spears, and rioting cataracts. Through slight negligence a boat can be crashed into pieces. It dries up in autumn and winter, causing difficulty in transportation. It is only in summer when mountain streams rush down from the Miao villages, that small craft may ply here and there. However, the cliffs and rocks become more dangerous as the water rises. Once a sandbank is reached, a day is often spent in lifting the boat across to deep water. The difficulty of crossing such banks is twice as much as in other rivers.”’

Gary Feinman (pers. comm.) writes that small-scale irrigation, such as check-dams and small canals were in use. However, these seem to be used for agriculture rather than transportation.

“The developed canal network was vital for Kaifeng to prosper in the 6th~12th centuries. Since the Sui and Tang Dynasties and the Five Dynasties, Bianzhou gradually became the transportation junction, and it was also called a “metropolis rejoined by water and land” [29]. […] In the Later Liang Dynasty (during the period of the Five Dynasties), in order to acquire the material support of the region in the south of the Yangtze River, Zhu Wen utilized the advantageous water transportation of Bianzhou and founded the capital in Kaifeng.”§Huang, W. et al. 2021.

“At its peak, Tiwanaku held power over a large part of present-day eastern and southern Bolivia, northwestern Argentina, northern Chile, and southern Peru. Its influence was largely due to its impressive “raised-field system” of agriculture, which used elevated planting beds separated from each other by small irrigation canals. The canals were designed to keep the crops from freezing on cold nights by preserving the heat from the daytime sun and for growing algae and aquatic plants used as fertilizer.”

“Pumapunku… is the second most important structure at Tiwanaku (Figure 6.13). It measures 155 m x 122 m… Excavations done by the CIAT, between 1977 and 1978, and by the Instituto Nacional de Arqueología, in 1989, exposed the perimeter of the base walls and sectors of the upper platform. A main drainage canal can be seen today in the southwestern corner.”

“The Porfirian focus on Mexico City’s built environment spilled over into other landscape features. Water itself was not necessarily detrimental to a city nor was water inherently insalubrious; flooding or “disorderly” water became the problem. Attempts to control and manage the waters around the capital persisted through time—from the early Aztec dikes that divided Lake Texcoco to the Spaniard Enrico Martinez’s open canal through the mountains in 1697. But no comparable project shared the ambitions and aspirations of the Grand Drainage Project that started in 1886… The momentous undertaking included a thirty-mile canal with four aqueducts and bridges, a six-mile tunnel coated with brick and Portland cement, and a mile and a half cut through the mountainous terrain.23 Rerouting infectious streams and conserving precious clean water required a firm state commitment and a significant financial investment. By completion, in 1901, the project’s footprint extended well beyond its symbolic importance: the canal used 22 million bricks, 25,000 cubic meters of mortar, 1.5 million meters of lumber, and untold numbers of laborers lives.”

"Putting the new economic doctrines into practice, Carlos III and Aranda ordered dramatic new public works such as the Canal of Aragon, they inaugurated regular stagecoach service to the major cities, and they established a royal school of agriculture at Aranjuez.

In the Russian Empire, significant canal construction occurred from the early 18th to the 19th century:
Vyshny Volodsky System (1757): Started at Tver on the Volga, it connected through Vyshny Volochok and followed the Volkhov River to the Neva, serving as the main link between Moscow and St. Petersburg. Marinskaya System (1731-1799): Linked the Volga tributary Sheksna with Lake Onega and the Neva, playing a key role in connecting Siberia with European Russia. Tikhvin System (1811): Connected the Volga tributary Mologa with Lake Ladoga, primarily used for timber transport. Oginski Canal (1804): Linked the Dnieper and Njemen, running from the Dnieper through the Pripet to Pinsk. Berezina Canal (1805): Connected the western Dvina and Dnieper, going through Lake Sepel into the Berezina. Württemberg Canal (1828): Joined the Marinskaya system with the Northern Dvina, modernized during the last war. These canals were part of a larger effort to improve transportation and trade, significantly enhancing Russia’s internal connectivity and economic development during this period. [1] [1]: Stefan T.

Present since previous polity. “Industry and trade in cities like Brünn / Brno, Pest, and Trieste / Trst also benefited from new links created by Austria’s growing transportation infrastructure, which in turn stimulated increased economic growth. New highway projects, canals, river regulation, and mountain pass systems produced a rapid increase in continental transport and trade, as well as cutting the time it took to travel between economically linked destinations, often by over 50 percent.”

present ♥ “Because the Chacoans were skilled builders, Gordon Vivian was sure that they must have had some way of collecting and distributing this water. He soon found evidence of an efficient irrigation system. Later, Gwinn expanded on his father’s work. The Chacoan irrigation system depended on dams and canals. After a rainstorm a dam at the mouth of each side canyon collected the water that fell from the cliff top. The water was then channeled into a stone-lined canal, which emptied into a head gate with narrow openings that could be blocked or left open to control the water’s flow into ditches. The ditches led to large plots of many individual gardens. In the summer of 1967, Gwinn Vivian excavated a dam that had been built across one of the main side canyons. It was a massive structure more than 120 feet long and 7 feet high. The water emptied into a canal through a gate near the middle of the dam. The long, curving, masonry-lined canal directed the water to 24 acres of bordered gardens that were laid out in neat rectangles. Gwinn Vivian calculated that a summer thunderstorm that produced 1 1/4 inches of rain in an hour would have provided the Penasco Blanco gardens with 540,000 gallons of water—half a gallon per square foot. The Chacoan genius for building and engineering allowed a large number of people to live in that otherwise dry and rugged canyon.”

“Maya agriculture was rainfall-dependent, and farmers used various water or agricultural systems including aguadas, artificial reservoirs, raised fields, dams, canals, and terraces (Dunning et al. 1997).”
[1]
“Peter Harrison (1993) correlates reservoir building with the accelerated construction of monumental architecture in Tikal’s core, especially beginning in the Early Classic. Quarrying of reservoirs provided building materials for monumental construction projects, including limestone fill, wall facing, and plaster (Scarborough 1993). At Calakmul, which is surrounded by bajos (low-lying seasonal swamps), there are extensive canal systems as well as thirteen reservoirs and aguadas (Braswell et al. 2004; Folan et al. 1995).”

The development of canals in Russia transitioned significantly during the early 18th century under Peter the Great. Prior to this period, Russia primarily relied on its natural river systems for transportation and trade, with rivers interconnected by simple boat portages. Peter the Great’s exposure to the canal systems in Holland inspired him to initiate the construction of engineered waterways in Russia. This marked a pivotal shift from reliance on natural waterways to the systematic building of canals, enhancing trade, transportation, and military logistics within the Russian Empire.

The first canal was a project to link the Don with the Oka and the Volga. A system of canals was built connecting the Volga and the Neva. This so-called Vyshny Volodsky system started at the city of Tver (now Kalinin) on the Volga and opened in 1706. [2] [1]: Stefan T. Possony, “European Russia’s Inland Waterways - Past, Present, and Future,” U.S Naval Institute Proceedings, https://www.usni.org/magazines/proceedings/1947/august/european-russias-inland-waterways-past-present-and-future.

No other country in the world has undertaken such an extensive program of construction of new canals and restoration of old ones, as has the Soviet Union. The Soviet waterways and the newly constructed and reconstructed canals, in particular, play both an economic and a strategic role. They not only provide additional navigable waterways and thus enlarge the transportation network, but they also now connect five seas—the Baltic, the White, the Black, the Sea of Azov, and the Caspian—on the European periphery of the Soviet Union. Thus, there exists an efficient inner waterway system, which permits the rapid transit of small naval vessels from one sea to another, since all the new and reconstructed navigable canals have a uniform depth of 3.65 meters (slightly over 12 feet). This allows 5,000-ton vessels to cruise freely and crisscross the entire European part of the country, and to sail at will to any of the five seas surrounding the area.

The near-absence of archaeologically identified settlements makes it particularly challenging to infer most building types. "While the historical sources provide a vague picture of the events of the first 500 years of the Kanem-Borno empire, archaeologically almost nothing is known. [...] Summing up, very little is known about the capitals or towns of the early Kanem- Borno empire. The locations of the earliest sites have been obscured under the southwardly protruding sands of the Sahara, and none of the later locations can be identified with certainty."

Canals used for transport were and are typical of Dutch cities. "Persistent sentiments of fear and insecurity will have been an added impetus for the inhabitants of Batavia to create a protected and safe environment in the city. As the name suggests, what was in essence a Dutch city was constructed there, albeit very gradually and with some reliance on improvisation: a grid of streets and canals, probably inspired by the ideas of Simon Stevin, of blocks of stone houses with tiled roofs, all enclosed by city walls and fortifications. Indeed, not only in terms of design and architecture but also in terms of its institutions, Batavia seemed a typical Dutch town, with a Board of Aldermen housed in the town hall and a civic militia."

"Contexts that could shed light on the dynamics of social structure and hierarchies in the metropolis, such as the royal burial site of Oyo monarchs and the residences of the elite population, have not been investigated. The mapping of the palace structures has not been followed by systematic excavations (Soper, 1992); and questions of the economy, military system, and ideology of the empire have not been addressed archaeologically, although their general patterns are known from historical studies (e.g, Johnson, 1921; Law, 1977)."
[1]
Regarding this period, however, one of the historical studies mentioned in this quote also notes: "Of the earliestperiod of Oyo history, before the sixteenth century, very little is known."
